I need to use asp.net to access and capture video from webcam but i want to make it browser independent and OS independent on client side.

I have seen in many articles calling avicap32.dll and also if I use DirectShow API of .net, will it be OS independent?

Or there any other solutions for the problem??

Shall be grateful if you help.

When you want to disable?Or In which event?

You need to pass the button id MyButton.ClientID to the JS Function.

EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

In page load add

button1.Attributes.Add("onclick","javascript:DisButton('" & button2.ClientID & "')")

JS Function

function DisButton(cntrl)
{
document.getElementById(cntrl).disabled=true;
return false;
}

on button1 click button2 will disable.

I'm not sure what you are trying to do.

You have repeater and that contains a button atleast. say button1

You have an another button thats outside the repeater. say button2

So on button2 click you want to disable the button1.

If this is the requirement....

1.You can use the FindControl function of repeater to get controls inside therepeater, and pass the ID of button1 to the JS function.

2.You can store the ID inside a hidden field and get it in the JS.

Hop this Helps you...

Hi
I have the following code which should count the number of rows in the gridview ands then I want it to assign a number to it, so if there three rows it would assing 1, 2, 3 to each row but its not working it shows error Cannot implicitly convert type 'int' to 'string'

any help would be great!

for (int x = 0; x < GridView1.Rows.Count; x++)
{
GridViewRow row = GridView1.Rows[x];
dropdown = ((DropDownList)row.FindControl("ddorder"));

int count =+ 1;
dropdown.DataValueField = count;
}

Your Code

for (int x = 0; x < GridView1.Rows.Count; x++)
            {
                  GridViewRow row = GridView1.Rows[x];
                  dropdown = ((DropDownList)row.FindControl("ddorder"));

                  int count =+ 1;                  
                  dropdown.DataValueField = count;
}

Tip:
Or the control does not exist
or it should be count.ToString();

Int32 count = 0;
DropDownList dropdown = new DropDownList();
foreach (GridViewRow row in GridView1.Rows)
{
   try
   {
      dropdown = ((DropDownList)row.FindControl("ddorder"));
      count++;
      dropdown.DataValueField = count.ToString();
   }
   catch (Exception err)
   {
      /// Do Someting with err.Message;
   }
}

Good Luck

You only fill DataValueField but you should also fill DataTextField.

In the OnSelectedIndexChanged- event you can then pick the .SelectedValue, which is the DataValueField.. If you pick in that event the .SelectedIndex.Text you have the DataTextField.

In this case you can show a database description field in the DataTextField while attaching it's databse field ID to the DataValueField.

OK thanks for that
Now say Ive got 3 rows I want to add 1,2,3 to each dropdown in each row therefore I want the number of rows to appear in the dropdownlist, how would I do that? WOuld it just be an extension to the code I have?

Re: Cannot implicitly convert type 'int' to 'string'

the extension would be like this.

DropDownList dropdown = new DropDownList();
foreach (GridViewRow row in GridView1.Rows)
{
   try
   {
      dropdown = ((DropDownList)row.FindControl("ddorder"));
      for (int count = 1; count <= 3; count++)
      {
           dropdown.Items.Add(new ListItem(count.ToString(),count.ToString()));
      }
   }
   catch (Exception err)
   {
      /// Do Someting with err.Message;
   }
}

OK, final question

How do I select the correct row dropdownlist when updating my database.
At the moment when I set it to dropdown.selecteditemvalue it takes the very last row value instead of the current one.
How would I fix this?
thanks for your great help so far! Smile | :)

also how do I get another column value from the same row?

DropDown.SelectedValue I guess you mean

You know you hav to run along each GridViewRow to see the value of the dropdown control?

Like i showed you
Int32 selectRow = 0;
foreach (GridViewRow row in GridView1.Rows)
{
GridView1.SelectedIndex = selectRow;
// find you dropdownControl
//row.SelectedValue will show now values
selectRow++;
}

There is no reason to set the text and the value to the same value. A ListItem without a value returns the text property as value.

dropdown.Items.Add(new ListItem(count.ToString()));

Despite everything, the person most likely to be fooling you next is yourself.

Well....If you want to add an item to the DropDownList you could do
dropdown.Items.Add(new ListItem(count.ToString(),count.ToString()));

in stead of dropdown.DataValueField = count.ToString();
dropdown.DataTextField = count.ToString();

DataxxxxField is used for DataBinding for values retrieved from a database

In page_Load remember to place code in
if (!Page.IsPostBack)
{
// the code
}

I would try this

protected void CheckLogin()
{
   if (Session["LoginAdminUser"] == null)
   {
       Response.Redirect("~/admin/oola_log_in.aspx");
   } 
   else 
   {
       LoginUser= Session["oLoginAdminUser"].ToString();   }
}

LoginUser = Type String
Session["oLoginAdminUser"] = Type Object so you need the ToString() addition

On development server it is allowing upto 10MB to upload but on production server it is not taking more than 1KB.
